FWL250 Optical Service Channel
A optical-fiber network demands routine maintenance, objectifying prevention and
imperfections’ correction. This demands frequent visits of technician and engineers to the
network’s stations (site, nodes). The communication between the located professionals in distinct
stations or between these and the central office of operations (network operation center) normally is
carried through electric service channels. The transport of this service channel takes place through the
optical supervision signal, what it demands intermediate layer of equipment.
Electric service channels are limited solutions, with few easiness and expensive in
relations of its applications. A usual difficulty, for example, is found when one of the interlocutors
is out of the station. In this in case, that is not possible to contact it by service channel, then
cellular telephones are used. In the majority of times, the cellular telephones’ use is intense,
causing enormous monthly bills for external professional. On the other hand, it is common
telecommunications’ stations are installed in remote places, without covering of cellular telephony,
this fact difficults the external technician’s work.
The "FWL250 Optical Service Channel" was developed for voice communication
between fiber network sites. It replaces, with superior performance and lower cost, the electrical service
channels available in the market. It offers integration with Public Switched Telephone Network and PABX
systems. These features allow field engineers and technicians to communicate not only between network sites
but also with the company's offices and external Public Telephone Network. FiberWork's FWL250 operates as an
open channel, where all network nodes have access to the same conversation simultaneously (multiple access).
It can also be configured as a private channel, where the signal pass through every node except the destination
node (P2P communication). The FWL250 is an ideal solution where dark fibers are abundant. However, it can be
used with active fibers as well, using a different wavelength from the working optical channels. In this case,
it will be necessary to employ the FiberWork’s ACTIVE Solution. For ultra-long-reach applications, the
FWL251 Regenerator may be used for signal regeneration. With all these differentials, the FWL250 Optical
Service Channel is, therefore, a practical and economic solution to operators who want to speed the services
and to reduce the expenses with the external activities of its employees. The ROI is counted in few months,
taking itself in account only the economy with cellular telephones’ expenses.
